Mutnovsky, Kamchatka, Russia

Location:52.45N, 158.19E
Elevation:7,616 ft. (2,322m)

Mutnovsky is a composite stratovolcano with a large twin crater at its
summit. These craters have crater lakes in them and very active
fumaroles. Pumice beds, cones and
lava flows can be found on the slopes of these craters. Explosive
eruptions producing ash occurred in 1945-52 and then again in 1960. This
volcano also goes by the names of Mutnaia sopka, Povorotnaia sopka and
Sopka Mutnovskaia. It is thought that this volcano possibly located in
an old ruined caldera with a diameter of about 9 km. The mountain itself
could have been formed by two merging cones. Originally there had been
one stratovolcano then later on a second emerged on the northwestern
slope of the first. Over time the caldera of the first volcano got filled
with ejecta from the second cone. A 3 x 1.5 km pear
shaped crater exists at the summit of Mutnovsky, here one can find its
two lakes and steam vents that emit huge quantities of volcanic gases.
